Description
Technical field
The utility model relates to a kind of control device, especially relates to a kind of control device of modified model frequency-charger cabinet cooling fan.
Background technology
At present, frequency conversion screw air compressor uses as standby host, does not need startup work for a long time.But, because the radiator fan controlling the frequency-charger cabinet of these frequency conversion screw air compressor start and stop is directly connected on power circuit breaker lower end, so radiator fan is in operating condition all the time, cause the significant wastage of electric energy.If when frequency conversion screw air compressor does not put into operation, manual-lock radiator fan circuit breaker, not only has the risk of electric shock, and when frequency conversion screw air compressor startup work, operating personnel likely do not open radiator fan power supply because of carelessness, frequency converter heat radiation is bad, easily causes frequency converter to damage.Radiator fan operates always, also can cause fault.
Utility model content
The purpose of this utility model be exactly provide that a kind of improvement expenses is low to overcome defect that above-mentioned prior art exists, correctional effect obviously, energy-saving and cost-reducing, the control device that reduces the modified model frequency-charger cabinet cooling fan of equipment fault and damage.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of control device of modified model frequency-charger cabinet cooling fan, it is characterized in that, comprise frequency-charger cabinet radiator fan, motor inverter, motor, switchgear, described motor is connected with motor inverter, and described motor inverter is connected with frequency-charger cabinet radiator fan by switchgear.
Described switchgear comprises that starting contactor KM1 assists normally opened contact KM1-1, starting contactor KM1 assists normally opened contact KM1-2, fan contactor KM3 main contacts and KM3 contactor coil, described starting contactor KM1 assists normally opened contact KM1-1 to be located in motor inverter, described starting contactor KM1 assists normally opened contact KM1-2 to connect with KM3 contactor coil, and described fan contactor KM3 main contacts is connected in series with frequency-charger cabinet radiator fan;
Described starting contactor KM1 action, while its auxiliary normally opened contact KM1-1 is closed, starting contactor KM1 assists normally opened contact KM1-2 also to close, thus it is electric to make KM3 contactor coil obtain, drives fan contactor KM3 main contacts to close further, drive the running of frequency-charger cabinet radiator fan.
Described starting contactor KM1 assists normally opened contact KM1-1 to be the startup contact of motor inverter.
Also comprise the first circuit breaker be connected in series with motor inverter.
Also comprise the second circuit breaker be connected in series with KM3 contactor coil.
Described starting contactor KM1 assists normally opened contact KM1-2 and KM1-1 synchronous operation.
Described KM3 contactor coil is energising after KM1-2 is closed.
Described frequency-charger cabinet radiator fan operates after KM3 contactor coil energising adhesive.
It is described when starting contactor KM1 assists normally opened contact KM1-1 to disconnect, motor inverter quits work, then motor shuts down, simultaneously because starting contactor KM1 assists the relation of normally opened contact KM1-2 and KM1-1 synchronous operation, KM1-1 is also in off-state, KM3 contactor coil dead electricity, and fan contactor KM3 main contacts dead electricity disconnects, frequency-charger cabinet radiator fan shuts down together, achieves the design that frequency-charger cabinet radiator fan also shuts down when motor shuts down.
Compared with prior art, the utility model has following improvement and advantage:
1) in the main circuit of radiator fan, seal in contactor KM3, playing can the effect of start and stop fan.
2) because KM1-1 and KM1-2 is action simultaneously, ensure that the consistency of frequency converter start and stop and radiator fan.
3) effectively saved the energy, after transformation, had 4 such regulator cubicle 1 year at least power saving (80*3/1000) * 24*320*4=7372.8 degree, reduce compressed-air actuated unit consumption.
4) improvement expenses is low, and correctional effect is obvious, also reduces the damage that radiator fan causes because of long-term unnecessary running.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 be frequency-charger cabinet radiator fan, 2 be motor inverter, 3 be motor, 4 assist normally opened contact KM1-1,5 to be fan contactor KM3 main contacts, 6 be that KM3 contactor coil, 7 assists normally opened contact KM1-2 for starting contactor KM1 for starting contactor KM1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
As shown in Figure 1, a kind of control device of modified model frequency-charger cabinet cooling fan comprises: frequency-charger cabinet radiator fan 1, motor inverter 2, motor 3, starting contactor KM1 assist normally opened contact KM1-14, fan contactor KM3 main contacts 5, KM3 contactor coil 6, starting contactor KM1 to assist normally opened contact KM1-27
Improvements of the present utility model:
1, the contactor KM3 sealed in the main circuit of radiator fan 1
2, after frequency converter starting contactor KM1 adhesive, utilize its auxiliary normally opened contact 2. (KM1-2) 7 control radiator fan KM3 contactor coil 6 and be energized.
The auxiliary normally opened contact KM1-1 of starting contactor KM1 is the startup contact of motor inverter 2, when frequency converter 2 entry condition meets, this contactor meeting action, starter motor frequency converter 2, can the characteristic of action together according to all normally opened contacts of contactor, the auxiliary normally opened contact KM1-27 increasing another group KM1 is energized to KM3 contactor coil 6, and KM3 contactor coil 6 is energized after adhesive, frequency-charger cabinet radiator fan 1 running.If when stopping, two auxiliary normally opened contacts (KM1-1) 4, (KM1-2) 7 that starting contactor KM1 is corresponding can disconnect together, because (KM1-1) 4 disconnects, motor inverter 2 stopping,, because (KM1-2) 7 disconnects, then KM3 contactor coil 6 dead electricity, fan contactor KM3 main contacts 5 also disconnects because of dead electricity, and frequency-charger cabinet radiator fan 1 also shuts down together.In the main circuit of radiator fan, seal in contactor KM3, playing can the effect of start and stop fan.While KM1-1 and KM1-2, action ensure that the consistency of frequency converter start and stop and radiator fan.
